Abstract: Использование: на транспортных средствах, в том числе в летательных аппаратах и космической технике. Технический результат: преобразование волновой электромагнитной энергии СВЧ (УКВ)-частотных диапазонов в магнитную движущую силу путем воздействия магнитных составляющих электродинамических полей, излучаемых каждым электрическим вибратором, на высокочастотные токи в другом вибраторе. В результате параллельного расположения вибраторов на расстоянии примерно четверти длины волны друг от друга и смещения фаз токов в них на четверть периода векторы магнитных сил, действующих на каждый вибратор, имеют одно и то же направление, создавая движущую силу. Для практического применения вибраторы должны быть выполнены из сверхпроводящих материалов и находиться в вакуумной камере.
